Buying guide

Bathroom lighting buying guide: bulbs, sconces, mirrors

This guide is for people whose bathroom light is too harsh, too dim or too shadowy, including renters who cannot touch the wiring. It explains what to look for on a bulb box, which kinds of lighting suit which problem, and when a job belongs to an electrician. It recommends product types, not brands, and it has no affiliate links. Prices are rough US ranges.

In most bathrooms, better bulbs and better placement fix more than a new fixture. Start there before spending serious money.

How to choose

  1. Read the color temperature. It is measured in kelvins (K). About 2700K is warm and yellowish, 3000K to 3500K is soft neutral white, 4000K is neutral to slightly cool, and 5000K and above looks blue-white. For most bathrooms, pick one range, usually 2700K to 3500K, and stay inside it. Mixing a 2700K bulb with a 5000K one looks patchy.
  2. Check color accuracy (CRI). The color rendering index runs up to 100. Many ordinary LED bulbs are rated around 80, which is fine for general rooms. For makeup, shaving or judging skin tone at the mirror, look for 90 or higher. It is printed on the box or in the listing.
  3. Plan brightness in lumens, not watts. A commonly cited rule of thumb is around 70 to 80 lumens per square foot of floor area, with more at the vanity. A standard 5 by 8 foot bathroom has 40 square feet, so roughly 2,800 to 3,200 lumens in total. A bulb sold as a 60-watt replacement is typically around 800 lumens.
  4. Fix placement before power. Light from both sides of the mirror at face height removes shadows far better than a brighter overhead bulb. Sconces are usually mounted at roughly 60 to 66 inches from the floor and 28 to 36 inches apart.
  5. Check the rating for the location. Fixtures and bulbs must suit damp or wet locations, and a shower interior needs a wet-rated product. Check the label and the package. A bulb behind glass should be labeled for enclosed fixtures.
  6. Know your renter limits. Bulbs and plug-in or battery lights are the safe tier. Replacing a fixture is electrical work, so renters need written permission and should keep the original parts.

Matching the type to the problem

Match the fix to the symptom. If the room feels cold and clinical, the bulbs are usually too blue, so go warmer. If your face is shadowed at the mirror, add light on both sides rather than more from above. If the room has no window, use a higher lumen total and a neutral 3000K to 3500K to avoid a cave feel. If you keep waking the household with the overhead, add a warm night light first.

If you have a bar of bulbs above the mirror, a single wide frosted bar is better than bare bulbs, and a plug-in or battery light at the side finishes the job.

Common mistakes

When not to buy anything

Before buying, switch off the light, let the bulbs cool, and look at what you have. If the bulbs are mismatched, matching them often improves the room for a few dollars, and wiping a dusty cover costs nothing. A paler paint helps more than a stronger bulb in a dark room if you own the space. Work through the bathroom lighting checklist, and if you are deciding between several upgrades, use the bathroom refresh planner.
